Hi all
Hopefully someone else has encountered this issue or has some ideas about how to resolve it.
We have a thin client environment setup (W7 Embedded) in kiosk mode. When the thins start up, they autologin and auto-launch the RDP client to connect to our RDS server.
The issue we're having is that if they sit idle at the "Enter your credentials" screen for more than 20 minutes, the first logon attempt will always fail with "the two computers couldn't connect in the amount of time allotted"
Second login works just fine.
This seems to happen regardless of RDP client version (have tried 6.1.7601 & 6.2.9200) or Server OS (2008 R2 & 2012).
My troubleshooting and thinking thus far is that it's somehow related to Kerberos ticket timeouts or something like that.
It's also entirely possible this is by design, I'm just not sure.
Testing I've done:
Adjusting ALL the different RDP idle timeouts
Workgroup machine RDC 6.1.7601 -> Server 2012 RDSH
Workgroup machine RDC 6.2.9200 -> Server 2012 RDSH
Domain-joined machine RDC 6.1.7601 -> Server 2008 R2 (just administering)
Same error on all the above
Any help or pointers would be much appreciated!
